Connecticut Energy Rates

What is the difference between fixed and variable rate plans?

A fixed rate plan provides you with stability and peace of mind. Utility rates are variable rates that can change periodically. A fixed rate product may be higher or lower than utility rates, but, unlike utility rates, a fixed rate product will not change during the life of your contract. You are protected against unexpected and costly price increases and have greater control over the cost of your energy.

Unlike a fixed rate, a variable rate plan fluctuates monthly and does not protect you against price volatility. This may be higher or lower than the utility rate.



As of July 1st, 2021, the current utility standard service rate for Connecticut utilities are listed below. This rate will expire on December 31st, 2021. 

$0.070030/per kWh for Eversource Residential

$0.078593/per kWh for United Illuminating Commercial 

Connecticut Renewal Rates

The actual rate that a customer is charged may depend on a customer's bill cycle. If a United Illuminating customer billing period spans more than 1 month, the rate will reflect a proration of the rate in both months. In Eversource Energy (formerly CL&P), your billed rate will be the effective rate at the time in which your meter is read. All rates are subject to change on a monthly basis, future rates will be updated at least 30 days before becoming effective. Please revisit this page for the most current information.
